RICHARD OSMAN The Man Who Died Twice *****

I normally save 5 stars for books which have depth and great writing, but this was such an enjoyable read I'm giving it top marks as well, even if it's unlikely to win any great literary prizes.

It's the follow-up to The Thursday Murder Club and is at least as good.

In case you don't know, it's about four friends who are residents of a retirement village who start off looking at cold cases provided by former spy, Elizabeth, but then graduate to solving real murders - as you do.

This time it involves twenty million pounds worth of diamonds which have gone missing, the local drug baroness, the mafia, and MI5. 

As the bodies start piling up our septuagenarian heroes (hooray!) set about finding the truth and administering their own version of justice, with the aid of two local police officers who they've befriended.

It's witty and warm and great fun.
